Dedupe Lines — unique lines, optional sort
Paste multi-line text and drop repeated rows: keep the first occurrence in list order, or collect distinct lines and sort them with Unicode locale rules. Optional numeric-aware sorting when sorted mode is on; case-sensitive or case-insensitive matching; trailing newline preserved — all local.

Keep first occurrence walks your list from top to bottom, emits each distinct line once, and preserves the original order of those representatives. Sort unique collapses duplicates first, then sorts the remaining lines with locale-aware comparison (and optional numeric digit ordering).
